- 2. 3 Risk The decision situations with reference to risk analysis in Capital Budgeting Decisions can be broken up into three types (i) Risk, (ii) Uncertainty and (iii) Certainty Risk: The risk situation is one in which the probabilities of occurrence of a particular event are known. Uncertainty: The risk situation is one in which the probabilities of occurrence of a particular event are not known. The difference between risk and uncertainty, therefore lies in the fact that variability is less in risk than in uncertainty. Risk with reference to Capital Budgeting, results from the variation between the estimated and the actual returns. The greater the variability between the two, the more risky is the project.
- 3. 4 Sensitivity Analysis Sensitivity analysis is simply the method for determining how sensitive our NPV analysis is to changes in our variable assumptions. In this analysis, each variable is fixed except one and by changing this one variable, the effect on NPV or IRR can be seen. It answers “what if” questions, e.g. “What if sales decline by 30%?” To begin a sensitivity analysis, we must first come up with a base-case scenario. This is typically the NPV using assumptions we believe are most accurate. From there, we can change various assumptions we had initially made based on other potential assumptions. NPV is then recalculated, and the sensitivity of the NPV based on the change in assumptions is determined. Depending on our confidence in our assumptions, we can determine how potentially risky a project can be.
- 4. 5 Scenario Analysis Scenario analysis takes sensitivity analysis a step further. Rather than just looking at the sensitivity of our NPV analysis to changes in our variable assumptions, scenario analysis also looks at the probability distribution of the variables. Like sensitivity analysis, scenario analysis starts with the construction of a base case scenario. From there, other scenarios are considered, known as the "best-case scenario" and the "worst-case scenario". Probabilities are assigned to the scenarios and computed to arrive at an expected value. Given its simplicity, scenario analysis is one the most frequently used risk-analysis techniques.
- 5. 6 Example 1 From the under mentioned facts, compute the NPVs of the two projects for each of the possible cash flows. Project X (‘000 Rs.) Project Y (‘000 Rs.) Initial Cash Outlays (t = 0) 40 40 Cash inflow estimates (t = 1-15) Worst 6 0 Most Likely 8 8 Best 10 16 Required rate of return 0.10 0.10 Economic Life (years) 15 15
- 6. 7 Solution 1 The NPV of each project, assuming a 10% required rate of return, can be calculated for each of the possible cash flows. Expected Cash Inflows Project X Project Y PV NPV PV NPV Worst Rs. 45,636 Rs. 5,636 Nil (Rs. 40,000) Most Likely Rs. 60,848 Rs. 20,848 Rs. 60,848 Rs. 20,848 Best Rs. 76,060 Rs. 36,060 Rs. 1,21,696 Rs. 81,696 Project X is less risky than Project Y. The actual selection of the project will depend on the decision maker’s attitude towards risk. If the decision maker is conservative, he will select Project X as there is no possibility of suffering losses. On the other hand if he is willing to take risks, he will choose Project Y as it has the possibility of paying a very high return as compared to Project X. Such analysis in spite of being crude does provide the decision maker with more than one estimate of the project’s outcome and thus an insight into the variability of the returns.
- 7. 8 Probability Assigning probability to expected cash flows provides a more precise measure of the variability of cash flows. The concept of probability is helpful as it indicates the percentage chance of occurrence of each possible cash flow. For instance, if some expected cash flow has 0.6 probability of occurrence, it means that the given cash flow is likely to be obtained in 6 out of 10 times. Likewise if a cash flow has a probability of 1, it is certain to occur. Probability helps in estimating the expected return on the project. The expected value of a project is a weighted average return, where the weights are the probabilities assigned to the various expected events, that is the expected monetary values of the estimated cash flows multiplied by the probabilities.

Find out the expected returns and the standard deviations for these two securities. Suppose an investor has Rs. 20,000 to invest. He invests Rs. 15,000 in security A and balance in Security B, what will be the expected return and the standard deviation of the portfolio?
- 11. 12 The expected returns RA and RB are just the possible returns multiplied by the associated probabilities as follows: RA = (0.20 x – 0.15) + (0.50 x 0.20) + (0.30 x 0.60) = 25 % RB = (0.20 x 0.20) + (0.50 x 0.30) + (0.30 x 0.40) = 31 % The standard deviations can now be calculated as follows: σA = [0.20 (- 0.15 – 0.25)2 + 0.50 (0.20 – 0.25)2 + 0.30 (0.60 – 0.25)2 ]1/2 = (0.0700)1/2 = 26.46 % σB = [0.20 (0.20 – 0.31)2 + 0.50 (0.30 – 0.31)2 + 0.30 (0.40 – 0.31)2 ]1/2 = (0.0049)1/2 = 7 % Solution 3 The expected return and standard deviation of the portfolio of the investor are: Expected return = (0.75 x 0.25) + (0.25 x 0.31) = 26.5 % Continued….
- 12. 13 Solution 3 Note: As the investor is investing Rs. 15,000 in A and Rs. 5000 in B, his portfolio will consist of 0.75 of A and 0. 25 of B. State Probability Expected Return Recession 0.20 (0.75 x – 0.15) + (0.25 x 0.20) = - 0.0625 Normal 0.50 (0.75 x 0.20) + (0.25 x 0.30) = 0.2250 Boom 0.30 (0.75 x 0.60) + (0.25 x 0.40) = 0.5500 Expected Return = (0.20 x – 0.0625) + (0.50 x 0.2250) + (0.30 x 0.5500) = 26.5 % The standard deviation of the portfolio is: σ = [0.20 (- 0.0625-0.265)2 + 0.50(0.225 – 0.265)2 + 0.30(0.550 – 0.265)2 ]1/2 = [0.0466]1/2 = 21.59% Alternatively, expected return and standard deviation can also be found by:
